Operation

Note:

Most low power SRAMs on the market today can be used with the M48T201Y/V

TIMEKEEPER® SUPERVISOR. There are, however some criteria which should be used in

making the final choice of an SRAM to use.

The SRAM must be designed in a way where the chip enable input disables all other inputs

to the SRAM. This allows inputs to the M48T201Y/V and SRAMs to be “Don't care” once

VCC falls below VPFD (min). The SRAM should also guarantee data retention down to VCC =

2.0V. The chip enable access time must be sufficient to meet the system needs with the chip

enable (and output enable) output propagation delays included.
